Abstract: The present invention aims to provide a method of hydrolysis of cellulose using a filamentous fungus-derived cellulase as a carbohydrase, which method comprises the step of adding the carbohydrase to cellulose to perform primary hydrolysis and then subjecting the primary hydrolysate to solid-liquid separation into a primary sugar liquid and solids; the step of adding water to the solids and performing secondary hydrolysis, followed by subjecting the secondary hydrolysate to solid-liquid separation into a secondary sugar liquid and a residue; and the step of filtering the primary sugar liquid and/or secondary sugar liquid through an ultrafiltration membrane, and recovering the carbohydrase from the feed side and recovering a sugar solution from the permeate side. By this, a method to reduce the amount of enzyme, such as cellulase, used in a method for producing a sugar liquid from pretreated cellulose is provided.

Abstract: In the process of production of a sugar liquid from woody biomass, conventional techniques have a drawback in that particular components contained in the saccharified liquid of the woody biomass cause deterioration of the filtration performance during filtration of the saccharified liquid through a microfiltration membrane and/or ultrafiltration membrane. In the present invention, mannanase is reacted with a liquid component obtained by hydrolysis of woody biomass to increase the filtration performance of the microfiltration membrane and/or ultrafiltration membrane for the saccharified liquid, so that efficient production of a sugar liquid is possible.

Abstract: Disclosed is a cellulose-based filter aid having high performance to remove suspended substances, and a method for producing it. The method for producing a filter aid comprises the steps of: (A) obtaining a pretreated biomass by pulverization treatment and/or thermochemical treatment of a cellulose-containing biomass; (B) treating the pretreated biomass obtained in the Step (A) with cellulase to obtain a cellulase-treated product; and (C) obtaining a solid content of the cellulase-treated product of the Step (B). The cellulose-based filter aid comprises a water-insoluble cellulase-treated product of a cellulose-containing biomass.
